[MSIL] Get the address of the element on the top of the stack

I'm trying to write something equivalent to the following in MSIL:

Code:

---

Console.ReadKey().KeyChar

---

However, after I call the ReadKey() method and I have the ConsoleKeyInfo on the stack, I haven't found any way to get its address that doesn't involve using a local variable. Is it possible?

Here's what I have:

Code:

---

gen.Emit(OpCodes.Call, typeof(Console).GetMethod("ReadKey", Type.EmptyTypes));
gen.Emit(OpCodes.Stloc_0);
gen.Emit(OpCodes.Ldloca, (ushort)0);
gen.Emit(OpCodes.Call, typeof(ConsoleKeyInfo).GetProperty("KeyChar").GetGetMethod());
